      Are sky over enthusiastic about expected speeds

      Hi

      Potential new user here, Sky LLU has just become available from my exchange.
      After checking on the sky availability checker it stated my line is capable of up to 5 Mb.

      However this to me seems extremely optimistic.

      My current ADSL 1 stats are :-
      Noise Margin: 7.4 dB
      Connection Rate: 2048 Kbps
      Line Attenuation: 60 to 63.5 dB (depending on what router I am using)
      Power: 16.9 dBm

      Exchange Information

      Exchange: Llanberis BT Code: WNLR

      Distance:- Direct: 2.78 km
      (appx)* By Road: 3.7 km

      BT Line Speed Estimation

      Fixed ADSL: 2048 kbps (2 Mb)
      DSL Max: 2000 kbps (2 Mb)

      The Kitz.co.uk Max speed calculator for 62dB line attenuation for adsl2+ states
      2112 kbps connection and 1869 kbps throughput.

      Router is plugged into master socket with NTE5 faceplate

      So how has SKY come up with 5 Mb and is it in any way achievable

      Thanks

      5 meg seems about right based on your distance from the exchange.

      The high attenuation could be a home wiring/setup issue.

      Re: Are sky over enthusiastic about expected speeds

      I have tried everything to get the line attenuation down lower, that figure is direct from the master socket using a NTE5 ADSL faceplate.
      and the sync rate is comparable with neighbouring houses.
      So I take it that Sky estimate just from exchange distances and I am not likely to get more than 2Mb.

      Did you check your estimated speed with your telephone number or your address?
      Have you tried the test socket behind your master socket?

      If speeds don't improve from your test socket, I would raise it with Sky. As you are coming in a bit lower than the estimated speed, they may arrange for an SFI engineer. Could be a case of renewing the lead-in wire to your property, or if other people in the area are getting low speeds too, perhaps they can move you onto a different pair in the cabinet.

      For the record Sky estimated my line speed to be 4Mb. They normally under-estimate the speed.

      If I didn't understand the true capabilities better I might have gone elsewhere knowing what I could get elsewhere.

      As far as improving your connection is concerned, take a look at the link below:

      ::. Kitz - Improve your adsl connection speed .::

      Connect your router to the test socket, then post back here with your stats.

      Sky Fibre Unlimited Pro: Connected at 80,000 kbps / 20,000 kbps
      Previous ADSL2+ Speed 19999 kbps 1153 kbps, Line Attenuation 17.5 db 6.9 db, Noise Margin 7.5 dB 8.7 dB
      Speedtest: 17.15MB/s 0.97Mb/s Ping 31 ms

      Re: Are sky over enthusiastic about expected speeds

      Hi

      I have already done everthing possible to improve my line stats Those stats on my first post are the best achievable and are the same as I get directly from the master socket as I am using a NTE5 adsl faceplate at the master socket.

      What I do not understand is that the BT checker for my line states 2Mb estimated speed, and SKY states 5Mb, from what I have read with my line the difference between ADSL1 and ADSL2+ would be negligable.

      It would be great if SKY could perform miracles and get me 5Mb but I very much doubt it.

      However I am still tempted to switch to from Entanet to SKY for the unlimitted download allowance.

      Re: Are sky over enthusiastic about expected speeds

      Seems distance would indicate around 5mbps.

      However, if all homes are affected by the same speed rate.

      Then TBH i would put this down to either a potential faulty feed from ex.

      Or, if your more unlucky a section of aluminium cabling in the local network area.

      Unlikely its down to fault with wiring as somone would of complained and likely this would of been sorted, not definate but likely.

      Only way to know for sure is to contact BT and see what they say if they will say anything at all.
